There will be a familiar face in the Nets practice facility on Saturday. Ex-Net Bostjan Nachbar will take the NBA up on its offer to use team gyms for voluntary workouts.

This doesn’t necessarily mean Nachbar will be back with the Nets, but the athletic small forward is returning to the NBA.

After playing in Europe the past three years, a stronger, more mature Nachbar, whose nickname is Boki, is hoping to join an established team team that will give him an opportunity to play regularly.

“I’m sure there are teams that could use what I can do,” Nachbar said Thursday. “I’m confident over time it’s going to show I still can play and help a team that plays for high goals.”

Nachbar’s agent, Marc Cornstein, estimated he’s spoken to 10-12 teams about his client. Among them are the Nets, Knicks, Celtics, Sixers, Pistons, Hornets and Spurs.

Teams still are figuring out what they want to do, who they can add and who fits in. They can start signing players Dec. 9. Nachbar, 31, is excited to be apart of the process again and to be back.

His is an interesting story.

Nachbar, the Nets’ sixth man from 2005-2008, was one of the first players to go to Europe in 2008 when teams overseas started offering lucrative contracts to NBA guys. Nachbar signed a three-year deal for 9.6 million tax-free euros with Moscow Dynamo.

They endured financial struggles that led to Efes Pilsen — the team in Turkey ex-Net Sasha Vujacic is playing with — taking on the last two years of Nachbar’s deal.

Then this summer when teams were going to Europe because of the lockout, Nachbar decided to return to the United States and train and prepare for his NBA return.

“I just went in a different direction,” Nachbar said. “I always knew I was going to return to Europe at some point in my career. I thought it was going to be towards the end of my career.

“When I left, I told everybody that I would try to come back one day. I really wanted to come back. I was never leaving to stay in Europe. I wanted to come back to the NBA. I would call it a short break from the NBA but it was always on my mind to come back.”

When Nachbar left the league — temporarily — he was playing the best ball of his NBA career. He averaged 9.5 points in 21.1 minutes his last two seasons off the bench for the Nets.

While he was overseas, Nachbar, who played for Slovenia in the World Championships last year, kept his home in New Jersey. He’s been working out with his personal trainer Nick DiPillo in New York and at St. Peter’s College in Jersey City and will be in East Rutherford Saturday.

Nachbar is a good shooter who also likes to beat defenders off the dribble, but he’s added some muscle to his body. He’s 230 pounds, about 10 pounds heavier than during his Nets’ days because of what lies ahead.

“This summer I tried to get a little bit stronger and just bulk up a little bit,” he said. “I realize for my height I was always a pretty dynamic, pretty quick player, especially for a European player. I wanted to keep that, and at the same time I wanted to gain some weight to get myself ready for the NBA season where the game is much more physical than in Europe and things develop much quicker on the floor.”

“He is in by far the best shape he’s ever been in his career,” Cornstein said. “His focus is unbelievable. I think he’s going to make someone extremely happy. With his size, the way he can shoot and score there are a lot of teams he can help.”

Nachbar began his professional career in Europe and then spent eight years in the NBA with the Rockets, Hornets and Nets. His career averages are 7.1 points on 40.6 percent shooting and 37.5 percent from three. He was a major contributor on the Nets’ last playoff team in 2007, and said he’s a better player now.

“Think of me three years ago plus add all the experiences I’ve been through the last three years and how I’ve matured,” he said. “I definitely think I’m a better player. I’m anxious to play the NBA game again. I hope and believe that it’s not going to take me a lot of time to get adjusted back to the NBA.”

Although the Nets are under a different regime from Nachbar’s time with them, he still has a link to them. Deron Williams would be able to get him plenty of open looks. Nachbar also has connections with the Sixers, where ex-Nets president Rod Thorn is in charge, and the Pistons, who hired Lawrence Frank as coach.

Nachbar certainly would be a good fit for the Knicks and Mike D’Antoni’s fast-paced game or coming off the bench for the Celtics. Those are teams that would appeal to him. But it’s still early in the process and Nachbar is looking forward to seeing what happens.

“I don’t think I would be too comfortable playing with a team experimenting and looking for things and building for the future way ahead,” Nachbar said. “I think I would fit much better on a team that knows what they want and has a system and needs a veteran player who knows his role. I definitely feel I can still play and help a team.

I’m sure it’s going to play out great. I hope I get in a position where I can make some decisions. They’re not going to be based on the money. I’m going to try and find a team I can fit in the best. I’m just looking for that.”
